assert.h is a header file in the C standard library. It defines the C preprocessor macro assert and implements runtime assertion in C. assert.h is defined in ANSI C as part of the C standard library. In the C++ programming language, assert.h and < cassert > are available; both are functionally equivalent. [1]
For example, a precondition—an assertion placed at the beginning of a section of code—determines the set of states under which the programmer expects the code to execute. A postcondition—placed at the end—describes the expected state at the end of execution. For example: x > 0 { x++ } x > 1.

Many video gaming mod, cheat codes, such as level cheat code, invincibility, etc. were originally introduced as debug code to allow the programmers and/or testers to skip hindrances that would prevent them from rapidly getting to parts of the game that needed to be tested; and in these cases cheat modes are often referred to as debugging mode.
This is a simple example of a union permitted in C++11: ... static_assert (constant-expression, error-message); Here are some examples of how static_assert can be used:

In C++11, this technique is known as generalized constant expressions (constexpr). [2] C++14 relaxes the constraints on constexpr – allowing local declarations and use of conditionals and loops (the general restriction that all data required for the execution be available at compile-time remains).
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
